Hi,
Which split rule do you use in classif.rpart? Can I choose gini or information gain to be the split rule?

We don't implement custom rules for learners, we just offer what the learners offer in their upstream package.
You can check the hyperparameters in a learners param set.
Check this section on learners in the mlr3book for more information.
